Responsibilities

• Owning the embedded software architecture of the system across the control, power and thermal subsystems
• Leading RTOS-based real-time control development, including timing analysis and fail-safe behaviour for launch and recovery sequences
• Owning the low-level integration layer: CAN, UART, SPI, I²C, sensor drivers, and motor and actuator control
• Designing and owning the firmware side of the command and control (C2) interface, including secure command handling and telemetry
• Establishing the secure firmware lifecycle: secure boot, signed images, field update strategy and rollback
• Building out embedded test infrastructure — unit test, hardware-in-the-loop, automated regression and continuous integration for firmware
• Running FMEA on software-controlled functions and driving firmware work packages
• Setting coding, review and release standards

Your profile

• 10+ years in embedded software for real-time, safety-relevant or mission-critical systems — defence, aerospace, automotive, robotics or industrial control
• Expert C and C++ on resource-constrained targets, with deep RTOS experience (FreeRTOS, Zephyr, ThreadX or equivalent)
• Strong hardware affinity: you read schematics, use a scope and logic analyser, and debug at register level
• Production experience across CAN, UART, SPI and I²C, and with STM32, ESP32 or comparable MCU families
• Track record building test and CI infrastructure for embedded work, not only features
• German and English
